Filter by:This phase 1 clinical trial consists of an initial open-label sentinel run-in (n=25) and a randomized, double-blind, dose-finding (n=125) investigating three antigen dose levels (low, medium and high) of VLA1601 and bedside mixing of the low-dose formulation with one of the two additional adjuvants (CpG1018®, 3M-052-AF/AP 60-702). VLA1601 will be administered according to a two-dose regimen (i.e., on Day 1 and Day 29). The primary objective of this trial is to assess the safety and tolerability of the vaccine candidate up to 7 days after each vaccination; and to assess the immune response induced by the vaccine candidate 28 days after the second vaccination. Additionally, safety and immune response of the vaccine candidate will be monitored throughout the trial.
Prospective, non-interventional study carried out after culturing placental trophoblastic tissue ex vivo and infection with Zika and Tonate
The purpose of this study is to describe the side effects and immune response of a candidate vaccine that might protect against Zika. The vaccine called PIZV (purified inactivated Zika virus vaccine) is given by injection in two doses that are 28 days apart in healthy adults. Participants will receive PIZV or placebo and will be followed for 7 days after each dose and up to 6 months after dose 2.
This study will include 4 cohorts of 14 ZIKV and DENV-naïve female and male subjects, 18 - 40 years of age (total: up to 56 subjects). Within each cohort, 10 subjects will receive ZIKV and 4 subjects will receive a placebo on Study Day 0. Cohorts 1 and 2 (Dose = 10^2 PFU) will be enrolled first and will enroll only women. Cohorts 3 and 4 (Dose = 10^2 PFU) will enroll men.
Given the magnitude of the epidemic in Puerto Rico, congenital Zika virus infection may have devastating complications to a significant population of children, also affecting families and society at large. This proposal takes a critical first step to ensuring that children with exposure to congenital Zika virus infection receive the follow-up care they need for optimal clinical outcomes. We anticipate that lessons learned from this study may also positively impact models for adherence to early intervention services in Puerto Rico.
This clinical study will evaluate the safety, tolerability, and reactogenicity of 2 dose levels of messenger RNA (mRNA)-1893 Zika vaccine in comparison to a placebo control in healthy participants who are flavivirus-seronegative and in participants who are flavivirus-seropositive.
Implement a randomized controlled trial, evidence-based, culturally adapted, environmental enrichment intervention for the purpose of enhancing neurocognitive outcomes among Zika Exposed Children.
To evaluate the safety, tolerability, and immunogenicity of two-doses of three-sequentially escalating cohort (2.5 µg, 5 µg and 10 µg) of BBV121 (purified inactivated adsorbed Zika virus vaccine) compared with Placebo (Alum). The investigational product is administered intramuscularly on Day 0 and 28 with safety and immunogenicity testing on Day 0, 28 and 56, and Month 6, 9 and 12
In this study the investigators will follow the neurodevelopmental outcome of children with in utero ZIKV exposure who do not have microcephaly or severe abnormalities consistent with Congenital Zika Syndrome. The ZIKV-exposed children will be compared to non-ZIKV exposed controls. Children will be assessed at age 3 and 4 years using standardized neurodevelopmental assessments. Children will also have neurodevelopmental assessment at age 5 and 7 years along with a brain MRI at age 7 years.
Zika virus (ZIKV) infection spread throughout the Americas with devastating consequences. Recent limited evidence suggests the potential for neurological effects associated with postnatally acquired ZIKV infection in humans; however, the impact on children is unknown. The researchers will conduct a longitudinal study of approximately 450 Nicaraguan children who were ages 2-12 in 2016 to evaluate the presence and persistence of neurological symptoms associated with ZIKV infection and to test whether ZIKV-infected children are at greater risk for developing neurological outcomes compared to uninfected children.
